  By the way, since the conventional beacon apparatus broadcasted the beacon signal, any terminal apparatus could receive the beacon signal. For this reason, when the received beacon signal is analyzed by a third party, the third party can transmit a beacon signal having the same data configuration as the analyzed beacon signal using a transmission device other than a valid beacon device. There was a problem.

  Further, since the data length of the beacon signal is short, a lot of data cannot be included in the beacon signal. In order for the terminal device to receive a large amount of data from the beacon device, the beacon device and the terminal device must be connected. However, while the beacon device and the terminal device are connected, the transmitting device cannot broadcast the beacon signal, and other terminal devices cannot receive the beacon signal. For this reason, other terminal devices that are not connected to the beacon device in an environment where there are a plurality of terminal devices must wait for a beacon signal to be received until the beacon device connected to the terminal device is disconnected. In other words, the use of beacon signals has been limited.

  The present invention has been made in view of such circumstances, and an object of the present invention is to broaden the use of beacon signals transmitted by legitimate beacon devices.

  The wireless communication system of the present invention includes a beacon device and a terminal device. The beacon device transmits first identification information and second identification information as beacon signals. When the terminal device in which at least one application operates receives the first identification information, the terminal device sets the predetermined application corresponding to the first identification information in a standby state for receiving the second identification information, and receives the second identification information. In such a case, a predetermined process corresponding to the second identification information of the predetermined application is executed.

  According to the present invention, the first identification information and the second identification information are obtained by the terminal device receiving the first identification information and the second identification information as a beacon signal transmitted by a legitimate beacon device and executing a predetermined process. The use of the beacon signal based on can be expanded and the convenience of the user can be enhanced.

[Summary example]
Hereinafter, according to an outline example of the present invention (an example in which a beacon device transmits two types of identification information using two types of beacon signals and a terminal device executes predetermined processing using the two types of identification information received from the beacon signals). A wireless communication system will be described with reference to FIGS.
In the present specification and drawings, components having substantially the same function or configuration are denoted by the same reference numerals, and redundant description is omitted.

<Configuration example of wireless communication system>
FIG. 1 shows a configuration example of a wireless communication system.
The wireless communication system shown in FIG. 1 includes a beacon device 1a and a terminal device 3a. The beacon device 1a transmits (transmits) the first identification information I1 and the second identification information I2 as beacon signals B1 and B2, respectively. The terminal device 3a is capable of receiving at least one application and receiving the first identification information I1 and the second identification information I2 from the beacon device 1a.

The beacon device 1a includes a storage unit 11, a first transmission unit 12, and a second transmission unit 13.
The storage unit 11 stores first identification information I1 allocated for the terminal device 3a to identify the beacon device 1a and second identification information I2 for causing the terminal device 3a to execute a predetermined process. And the memory | storage part 11 uses the non-volatile memory which does not lose | disappear data even if power supply is interrupted | blocked. However, a volatile memory may be used for the storage unit 11 as long as power supply to the storage unit 11 is maintained.

  The first transmitter 12 periodically broadcasts a beacon signal B1 around the beacon device 1a, and the second transmitter 13 periodically broadcasts a beacon signal B2 around the beacon device 1a. Here, as communication standards used between the first transmission unit 12 and the reception unit 31 of the terminal device 3a and between the second transmission unit 13 and the reception unit 31, for example, Bluetooth (registered trademark) or BLE ( Short-range wireless communication standards such as Bluetooth (registered trademark) Low Energy are suitable.

For example, the 1st transmission part 12 of the beacon apparatus 1a corresponding to BLE specification can transmit the advertising data containing the 1st identification information I1 to the circumference | surroundings of the beacon apparatus 1a as beacon signal B1. Moreover, the 2nd transmission part 13 corresponding to BLE specification can transmit the advertising data containing the 2nd identification information I2 to the circumference | surroundings of the beacon apparatus 1a as beacon signal B2.
In addition, you may comprise the 1st transmission part 12 and the 2nd transmission part 13 as one transmission part which transmits beacon signal B1, B2 by a time division (for example, alternately).

  The terminal device 3 a includes a reception unit 31, a storage unit 32, a processing unit 33, an input unit 34, and an output unit 35 that are connected to each other via a bus 30. As the terminal device 3a, for example, various information processing devices such as a smartphone and a tablet device can be used.

  The receiving unit 31 receives the first identification information I1 included in the beacon signal B1 transmitted from the first transmitting unit 12 of the beacon device 1a via an antenna (not shown). Similarly, the receiving unit 31 receives the second identification information I2 included in the beacon signal B2 transmitted from the second transmitting unit 13 of the beacon device 1a via an antenna (not shown).

  The storage unit 32 includes, for example, a storage medium or memory card used as a ROM (Read Only Memory), a RAM (Random Access Memory), or the like. The storage unit 32 stores a program, parameters, and the like for controlling each unit of the terminal device 3a. The storage unit 32 stores first identification information I1 and second identification information I2 set in advance.

  The processing unit 33 is configured by, for example, a central processing unit (CPU) that can be driven with low power consumption. The processing unit 33 can control the operation of each unit in the terminal device 3a based on the program, parameters, and the like read from the storage unit 32. Further, the processing unit 33 can activate and operate the application A1 read from the storage unit 32. The application A1 is one of programs executed by the processing unit 33. Then, the application A1 includes the first identification information I1 and the second identification information set in the storage unit 32, the first identification information I1 and the second identification information I2 received by the terminal device 3a from the beacon signals B1 and B2, respectively. If it is equal to I2, a predetermined process is executed.

  The input unit 34 outputs, to the processing unit 33, an operation signal generated according to an operation input performed by a screen touch on the operation surface, in addition to buttons and switches (not illustrated) arranged in the terminal device 3 a.

  For example, the output unit 35 displays and outputs a screen made up of text, images, and the like on the display surface. In the terminal device 3a, the input unit 34 and the output unit 35 may be configured as a touch panel display in which an operation surface and a display surface are overlapped.

<First processing example of terminal device>
Next, a first processing example of the terminal device 3a will be described.
FIG. 2 shows an example of processing until the terminal device 3a receives the first identification information I1 and the second identification information I2 and performs predetermined processing by the application A1.

  First, the processing unit 33 waits for the first identification information I1 included in the beacon signal B1 through the receiving unit 31 (S101). Then, the processing unit 33 determines whether the receiving unit 31 has received the first identification information I1 (S102). If the receiving unit 31 has not received the first identification information I1, the processing unit 33 continues the processing of steps S101 and S102.

  When the receiving unit 31 receives the first identification information I1, the processing unit 33 sets the predetermined application A1 corresponding to the first identification information I1 to the reception standby state of the second identification information I2 included in the beacon signal B2. To do. When the terminal device 3a receives the first identification information I1 and the application A1 is not activated, the terminal device 3a controls the processing unit 33 to control the predetermined application A1 according to the received first identification information I1. When activated (S103), the application A1 is placed in a standby state for receiving the second identification information I2. If the application A1 has already been activated, the process of step S103 is unnecessary, and the process proceeds to the subsequent step S104. The same applies to each embodiment described below.

  Next, the application A1 in the reception standby state waits for the second identification information I2 through the reception unit 31 (S104). Then, the application A1 determines whether the receiving unit 31 has received the second identification information I2 (S105). If the receiving unit 31 has not received the second identification information I2, the application A1 continues the processes of steps S104 and S105.

  When the receiving unit 31 receives the second identification information I2, the application A1 executes a predetermined process according to the second identification information I2 (S106), and ends the process of FIG.

<Second Processing Example of Terminal Device>
Next, a second processing example of the terminal device 3a will be described.
FIG. 3 shows a modified example of processing until the terminal device 3a receives the first identification information I1 and the second identification information I2 and performs predetermined processing by the application A1.

  In this process, the processes in steps S101 to S106 are the same as those shown in FIG. However, FIG. 3 is different in that the process of step S107 is added between the processes of step S104 and step S105.

  After the process of step S104, the application A1 determines whether or not the reception unit 31 has become unable to receive the first identification information I1 included in the beacon signal B1 (S107). When the terminal device 3a cannot receive the first identification information I1 when the application A1 is in the reception standby state of the second identification information I2, the terminal device 3a cancels the reception standby state of the application A1, and The process ends. However, if the receiving unit 31 can receive the first identification information I1, the terminal device 3a is located near the beacon device 1a, and therefore, the processing after step S105 is performed.

  As described above, when the reception unit 31 cannot receive the first identification information I1, the power consumption of the terminal device 3a is suppressed by canceling the reception standby state of the second identification information I2 by the application A1. Is possible.

  The beacon device 1a according to the outline example described above includes the first transmission unit 12 and the second transmission unit 13 separately. For this reason, even while the second transmitter 13 transmits a large amount of data in the beacon signal B2, the first transmitter 12 may continue to transmit the beacon signal B1 to the other terminal device 3a. it can.

  In addition, the terminal device 3a receives the first identification information I1 and the second identification information I2, and causes the application A1 to execute a predetermined process. The beacon signal B1 does not include data for the application A1 to execute a predetermined process. For this reason, the application A1 of the terminal device 3a cannot execute a predetermined process only by analyzing a beacon signal B1 by a third party. As a result, it is possible to prevent spoofing and free-riding by a third party who attempts to cause the application A1 of the terminal device 3a to execute a predetermined process only by receiving the beacon signal B1. In order for a third-party terminal device to perform a predetermined process, it is necessary to receive the second identification information I2 and to correctly understand the information included therein.

[First Embodiment]
Based on the outline example of the present invention described above, the first embodiment of the present invention (the encrypted second identification information I2e generated by the terminal device having the encryption key K1 based on the first identification information I1). A wireless communication system according to an example of decoding the above will be described with reference to FIGS.

<Configuration example of wireless communication system>
FIG. 4 shows a configuration example of a wireless communication system.
The wireless communication system shown in FIG. 4 includes a beacon device 1b in addition to the terminal device 3a shown in FIG. The beacon device 1b includes a random number generation unit 14 and an encryption processing unit 15 in addition to the storage unit 11, the first transmission unit 12, and the second transmission unit 13 included in the beacon device 1a illustrated in FIG.

The storage unit 11 stores an encryption key K1 in addition to the first identification information I1.
The 1st transmission part 12 includes the 1st identification information I1 read from the memory | storage part 11, and transmits in the beacon signal B1.

The random number generation unit 14 generates a random number Ra (an example of data updated at a predetermined cycle) at a predetermined cycle, and outputs the random number Ra to the encryption processing unit 15. The random number Ra generated by the random number generator 14 is periodically updated.
The encryption processing unit 15 generates encrypted second identification information I2e based on the first identification information I1 read from the storage unit 11, the encryption key K1, and the random number Ra input from the random number generation unit 14. Then, the encrypted second identification information I2e is output to the second transmitter 13.
The 2nd transmission part 13 includes the encryption 2nd identification information I2e input from the encryption process part 15 in the beacon signal B2, and transmits.

  The storage unit 32 of the terminal device 3a stores first identification information I1 and an encryption key K1 that are set in advance.

<Data configuration example of beacon signal>
FIG. 5 shows a data configuration example of two types of beacon signals B1 and B2 and second identification information I2. The process of generating the second identification information I2 from the first identification information I1 (beacon signal B1) shown in FIG. 5 and encrypting the second identification information I2 to generate the encrypted second identification information I2e (beacon signal B2) This is performed by the encryption processing unit 15.

  The beacon signal B1 includes the first identification information I1 as a whole. However, the beacon signal B1 may have a configuration in which other data is added to the first identification information I1 as indicated by a broken line.

  The encryption processing unit 15 generates the second identification information I2 based on the first identification information I1 read from the storage unit 11 and the random number Ra input from the random number generation unit 14. The encryption processing unit 15 may or may not encrypt the second identification information I2. Hereinafter, the case where the encryption processing unit 15 encrypts the second identification information I2 and the case where it is not encrypted will be described separately.

(When the encryption processing unit 15 encrypts the second identification information I2)
The encrypted second identification information I2e is obtained by replacing the first identification information I2 configured by replacing the first part (for example, the head part), which is a part of the first identification information I1, with the additional information Da. It is generated by encryption using K1.
Also, the encrypted second identification information I2e replaces the first part of the first identification information I1 with the additional information Da, and further a second part (for example, the end part) that is another part of the first identification information I1. May be generated by encrypting the second identification information I2 configured by replacing with the random number Ra updated at a predetermined cycle by the random number generation unit 14 using the encryption key K1.

  Note that the replacement process is not performed on the common data portion of the first identification information I1 and the second identification information I2. Further, the place where the first identification information I1 is replaced with the additional information Da and the random number Ra is not limited to the head portion and the tail portion of the first identification information I1.

Then, the second transmission unit 13 broadcasts a beacon signal B2 including the encrypted second identification information I2e.
The terminal device 3a receives the beacon signal B2 transmitted by broadcast and decrypts the encrypted second identification information I2e using the encryption key K1. Thereafter, a predetermined process corresponding to at least the additional information Da of the decoded second identification information I2 is executed.

(When the encryption processing unit 15 does not encrypt the second identification information I2)
The second identification information I2 is configured by replacing the first part of the first identification information I1 with the additional information Da.
The second transmitter 13 broadcasts a beacon signal B2 including the second identification information I2.
When the terminal device 3a receives the second identification information I2, the terminal device 3a performs a predetermined process corresponding to at least the additional information Da of the second identification information I2.

<Example of terminal device processing>
Next, a processing example of the terminal device 3a will be described.
FIG. 6 shows an example of processing until the terminal device 3a receives the first identification information I1 and the encrypted second identification information I2e and performs predetermined processing by the application A1.

  Since steps S201 to S203 in FIG. 6 are the same as steps S101 to S103 in FIG. 2 described above, detailed description thereof will be omitted.

  When the application A1 is activated in step S203, the application A1 receives the beacon signal B2 from the receiving unit 31 (S204). Then, the application A1 decrypts the received data using the encryption key K1 read from the storage unit 32 (S205). This received data is the encrypted second identification information I2e included in the beacon signal B2 received by the receiving unit 31 shown in FIG.

  Next, the application A1 determines whether or not the received data has been decrypted (S206). If the received data cannot be decrypted, the application A1 returns the process to step S204. If the received data can be decrypted, the application A1 executes a predetermined process according to the decrypted additional information Da of the second identification information I2 (S207), and ends the process of FIG.

  In the wireless communication system according to the first embodiment described above, a third-party terminal device that does not have the encryption key K1 cannot decrypt the encrypted second identification information I2e. For this reason, the eavesdropping of the encrypted second identification information I2e by a third party can be prevented.

  As described above, when the random number generation unit 14 periodically updates the random number Ra, the encryption processing unit 15 periodically updates the encrypted second identification information I2e according to the update of the random number Ra. For this reason, it is possible to prevent a third party from providing the second identification information I2 and providing a service according to the additional information Da to the terminal device that cannot decrypt the encrypted second identification information I2e. Even if a third party obtains some encrypted second identification information I2e, all ciphers transmitted by the beacon device 1b are obtained unless all the encrypted second identification information I2e for the number of random numbers Ra are obtained. Since the predetermined operation cannot be executed on the second identification information I2e, the beacon device 1b cannot be completely impersonated and can not ride.

  Further, since the random number Ra is periodically updated, it is difficult to acquire the additional information Da even if a third party receives the beacon signal B2. For this reason, it is possible to prevent forgery of the first identification information I1 by a third party beacon device, spoofing of the beacon device 1b, and free riding. The random number Ra does not have to be a random number, and may be a numerical value issued sequentially. Even in this case, the beacon device 1b can be sufficiently impersonated and prevented from riding.

[Modification of First Embodiment]
Next, a radio communication system according to a modification of the first embodiment of the present invention (an example in which a server having the encryption key K1 decrypts the encrypted second identification information I2e) will be described with reference to FIG. To do.

FIG. 7 shows a configuration example of a wireless communication system.
The wireless communication system illustrated in FIG. 7 includes a terminal device 3b, an access point (or base station) 5, and a server 7 in addition to the beacon device 1b illustrated in FIG.

The terminal device 3b includes a server communication unit 36 in addition to the reception unit 31, the storage unit 32, the processing unit 33, the input unit 34, and the output unit 35 included in the terminal device 3a illustrated in FIG.
The storage unit 32 stores only preset first identification information I1, and does not store the encryption key K1.

  The server communication unit 36 can communicate with the server 7 via the access point (or base station) 5 and the network 6. In the following description, an “access point” is used as a term including a base station in mobile communication such as a mobile phone and a communication interface for Wi-Fi (registered trademark) communication.

  In this wireless communication system, the server 7 has the encryption key K1, and the server 7 performs decryption processing of the encrypted second identification information I2e using the encryption key K1 (corresponding to steps S205 and S206 in FIG. 5). When the server 7 receives the encrypted second identification information I2e from the terminal device 3b via the access point (or base station) 5 and the network 6, the server 7 decrypts the encrypted second identification information I2e using the encryption key K1. . Then, the server 7 transmits the decrypted second identification information I2 to the terminal device 3b via the network 6 and the access point (or base station) 5.

  In such a wireless communication system, since the terminal device 3b does not have the encryption key K1, the security risk that the encryption key K1 is stolen from the terminal device 3b can be reduced. Further, even in an environment where a large number of terminal devices 3b exist, the server 7 can centrally manage the encryption key K1. Then, the application A1 can perform a predetermined process based on the decrypted second identification information I2 received from the server 7.

  Note that the server 7 not only decrypts the encrypted second identification information I2e, but also performs a part of predetermined processing (corresponding to step S207 in FIG. 6) according to the decrypted second identification information I2. May be.

[Second Embodiment]
Next, a wireless communication system according to a second embodiment of the present invention (an example in which a beacon device notifies a terminal device of the state of an electronic device) will be described with reference to FIGS.

<Configuration example of wireless communication system>
FIG. 8 shows a configuration example of a wireless communication system.
The wireless communication system shown in FIG. 8 includes a beacon device 1c and an electronic device 9 in addition to the terminal device 3a shown in FIG.

  The beacon device 1c includes a storage unit 11, a first transmission unit 12, a second transmission unit 13, a random number generation unit 14, and an encryption processing unit 15 included in the beacon device 1b illustrated in FIG.

The storage unit 11 stores preset first identification information I1 and an encryption key K1.
The first transmission unit 12 includes the first identification information I1 read from the storage unit 11 and the random number Rb1 (an example of additional information) input from the random number generation unit 14 and transmits the beacon signal B1.
The random number generation unit 14 generates a random number Rb1, a random number Rb2 (an example of data updated at a predetermined cycle), outputs the random number Rb1 to the first transmission unit 12, and the first transmission unit 12 and the encryption processing unit 15 Random numbers Rb1 and Rb2.

A state signal Sin indicating the state of the electronic device 9 is input to the beacon device 1c. This state signal Sin is used as a trigger for the beacon device 1c to notify the terminal device 3a of the state of the electronic device 9.
For example, when the electronic device 9 is an air cleaner, the status signal Sin output from the electronic device 9 includes, for example, information indicating that it is time to replace the filter.
And the beacon apparatus 1c transmits the information comprised by adding additional information to the 1st identification information I1 as beacon signal B1. This additional information is, for example, a random number Rb1.

  Based on the first identification information I1 read from the storage unit 11, the random numbers Rb1 and Rb2 input from the random number generation unit 14, and the status signal Sin input from the electronic device 9, the encryption processing unit 15 Identification information I2A, I2N is generated. The encryption processing unit 15 may or may not encrypt the second identification information I2A and I2N. Hereinafter, the case where the encryption processing unit 15 encrypts the second identification information I2A and I2N and the case where it is not encrypted will be described separately.

(When the encryption processing unit 15 encrypts the second identification information I2A and I2N)
When the beacon device 1c notifies the terminal device 3a of the state of the electronic device 9, the second identification information I2A configured by replacing a part of the first identification information I1 (for example, the head portion) with the random number Rb1. Is encrypted using the encryption key K1 to generate the encrypted second identification information I2Ae. Then, the beacon device 1c transmits the encrypted second identification information I2Ae as the beacon signal B2.

  Further, the beacon device 1c is configured by replacing a part of the first identification information I1 with a random number Rb2 that is updated at a predetermined period when the state of the electronic device 9 is not notified to the terminal device 3a. The second identification information I2N is encrypted using the encryption key K1 to generate the encrypted second identification information I2Ne. Then, the beacon device 1c transmits the encrypted second identification information I2Ne as a beacon signal B2.

  Then, when the terminal device 3a decrypts the encrypted second identification information I2Ae and receives the second identification information I2A at the time of state notification, the terminal device 3a responds to the state of the electronic device 9 notified by the second identification information I2A. The predetermined processing is executed.

(When the encryption processing unit 15 does not encrypt the second identification information I2A and I2N)
At the time of status notification, the beacon device 1c transmits second identification information I2A configured by replacing a part of the first identification information I1 with additional information as a beacon signal B2. This additional information is updated when shifting from the state notification time to the state non-notification time.
And the terminal device 3a performs the predetermined | prescribed process according to the state of the electronic device 9 notified by the 2nd identification information I2A, when the 2nd identification information I2A at the time of state notification is received.

<Data configuration example of beacon signal>
FIG. 9 shows a data configuration example of two types of beacon signals B1 and B2 and second identification information I2A and I2N. Second identification information I2A and I2N are generated from the first identification information I1 (beacon signal B1) shown in FIG. 9, and the second identification information I2A and I2N are encrypted and encrypted second identification information I2Ae and I2Ne (beacon signal B2). ) Is generated by the encryption processing unit 15.

  The beacon signal B1 includes the first identification information I1 and the random number Rb1 as a whole. However, the beacon signal B1 may be configured such that other data is added to the first identification information I1 and the random number Rb1 as indicated by a broken line.

  At the time of status notification, first, the second identification information I2A configured by replacing the leading portion of the first identification information I1 with the random number Rb1 input from the random number generation unit 14 is generated. The encrypted second identification information I2Ae is generated by encrypting the second identification information I2A using the encryption key K1. Then, the second transmission unit 13 broadcasts the encrypted second identification information I2Ae as a beacon signal B2.

  On the other hand, when the state is not notified, first, the second identification information I2N configured by replacing the leading portion of the first identification information I1 with the random number Rb2 input from the random number generation unit 14 is generated. The encrypted second identification information I2Ne is generated by encrypting the second identification information I2N using the encryption key K1. Then, the second transmission unit 13 broadcasts the encrypted second identification information I2Ne as a beacon signal B2.

  Note that the replacement process is not performed on the common data portion of the first identification information I1 and the second identification information I2A and I2N. Further, the place where the first identification information I1 is replaced with the random number Rb1 or the random number Rb2 is not limited to the head portion of the first identification information I1. The random numbers Rb1 and Rb2 are updated by the random number generator 14, but the random numbers Rb1 and Rb2 are different values.

Here, the beacon signals B1 and B2 change as follows according to the state signal Sin.
(1) When transitioning from state non-notification to state notification For example, when the electronic device 9 is an air cleaner, it is assumed that the user of the terminal device 3a is notified of the filter replacement time of the air cleaner.
At this time, the beacon signal B1 is a combination of the first identification information I1 and the random number Rb1, and the beacon signal B1 does not change. On the other hand, the beacon signal B2 becomes encrypted second identification information I2Ae by the encryption processing unit 15. For this reason, the terminal device 3a can grasp that the electronic device 9 has shifted from state non notification to state notification.

(2) Case of transition from status notification to status non-notification For example, a case is assumed in which filter replacement of the air purifier is completed.
At this time, the random number Rb1 of the beacon signal B1 is updated by the random number generator 14. The beacon signal B2 becomes encrypted second identification information I2Ne by the encryption processing unit 15. Here, the random number Rb2 included in the second identification information I2N before the encrypted second identification information I2Ne is encrypted is a value periodically updated by the random number generation unit 14. For this reason, the terminal device 3a can grasp that the electronic device 9 has shifted from the state notification to the state non-notification. However, since a third-party terminal device that does not have the encryption key K1 cannot decrypt the encrypted second identification information I2Ae and I2Ne, it is determined whether the second identification information indicates a state notification state. I can't figure out what to show. Thereby, the impersonation of the beacon apparatus 1c and a free ride can be prevented.

<Example of terminal device processing>
Next, a processing example of the terminal device 3a will be described.
FIG. 10 shows an example of processing until the terminal device 3a receives the first identification information I1 and the encrypted second identification information I2Ae, I2Ne and performs predetermined processing by the application A1.

Steps S301 to S306 in FIG. 10 are the same as steps S201 to S206 in FIG. 6 described above, and thus detailed description thereof is omitted.
In step S302, if the receiving unit 31 can receive the first identification information I1, the receiving unit 31 can also receive the random number Rb1.

  If the application A1 can decrypt the received data in the process of step S306, the application A1 determines whether the decrypted received data is the second identification information I2A transmitted from the beacon device 1c at the time of status notification (S307). . If the received data is not the second identification information I2A, the process returns to step S304, and the process in which the application A1 receives the beacon signal B2 is continued.

  If it is the second identification information I2A, the application A1 executes a predetermined process according to the notified state (S308), and ends the process of FIG. In step S308, for example, a message that prompts the user to replace the filter of the air cleaner is displayed on the output unit 35 of the terminal device 3a.

Here, when the beacon device 1c notifies the terminal device 3a of a plurality of states of the electronic device 9, the following operation is performed.
For example, at the time of status notification, the encryption processing unit 15 uses the random numbers Rb1, (Rb1 + 1),..., (Rb1 + N−1) generated by the random number generation unit 14 according to the status of the electronic device 9 to be notified by the beacon device 1c. N (N is a natural number) types of second identification information I2A are generated. The random number Rb2 is different from any of the random numbers Rb1, (Rb1 + 1),..., (Rb1 + N−1).
If these N types of second identification information I2A are used, the beacon device 1c can notify the terminal device 3a of the N types of states of the electronic device 9.

  For example, a case where a color printer is used as the electronic device 9 is assumed. At this time, the status signal Sin output from the electronic device 9 includes information that prompts replacement of the ink cartridge when, for example, any of the inks of the respective colors (C, M, Y, K) is insufficient. In this case, these pieces of information can be represented by four types of second identification information I2A. Various sensors may be provided as the electronic device 9. In this case, the state signal Sin output from the electronic device 9 can include various types of information detected by the sensors.

  Further, when the state is not notified, the beacon device 1c may not transmit the beacon signal B2. However, when a third-party terminal device receives the beacon signal B2, it is possible to detect the presence of any notification transmitted from the beacon device 1c and the number of notifications based on the fact that the beacon signal B2 has been transmitted. It should be noted that

  The beacon device 1c according to the second embodiment described above encrypts the second identification information I2A and I2N generated when the electronic device 9 is notified of the state and when the state is not notified, thereby encrypting the second identification information I2Ae. , I2Ne containing beacon signal B2 is broadcast. Here, at the time of status notification, the application A1 can grasp the status of the electronic device 9 based on the second identification information I2A in which the random number Rb1 included in the received beacon signal B1 is replaced. In addition, when the state is not notified, the application A1 recognizes that the beacon signal B2 is a signal generated when the state is not notified, based on the second identification information I2N including the random number Rb2 different from the random number Rb1 used when the state is notified. can do.

  The encryption processing unit 15 generates the beacon signal B2 by encrypting the second identification information I2A and I2N, but outputs the second identification information I2A and I2N to the second transmission unit 13 without encrypting the second identification information I2A and I2N. May be. In this case, the second transmission unit 13 transmits the unencrypted second identification information I2A and I2N as the beacon signal B2.

[First Modification of Second Embodiment]
Next, FIG. 11 shows a wireless communication system according to a first modification of the second embodiment of the present invention (an example in which a server having the encryption key K1 decrypts the encrypted second identification information I2Ae, I2Ne). The description will be given with reference.

<Configuration example of wireless communication system>
FIG. 11 shows a configuration example of a wireless communication system.
11 includes the beacon device 1c and the electronic device 9 shown in FIG. 8, the terminal device 3b, the access point (or base station) 5, and the server 7 shown in FIG.

The storage unit 32 of the terminal device 3b stores only the first identification information I1 set in advance, and does not store the encryption key K1.
The server communication unit 36 transmits the encrypted second identification information I2Ae and I2Ne (abbreviated as “I2e” in the drawing) to the server 7 via the access point (or base station) 5 and the network 6. The decrypted second identification information I2A and I2N (abbreviated as “I2” in the figure) is received.

  In this wireless communication system, the server 7 has the encryption key K1, and the server 7 performs decryption processing of the encrypted second identification information I2Ae and I2Ne using the encryption key K1 (corresponding to steps S305 and S306 in FIG. 10). . In other words, when the server 7 receives the encrypted second identification information I2Ae and I2Ne from the terminal device 3b via the access point (or base station) 5 and the network 6, the encrypted second identification information I2Ae using the encryption key K1. , I2Ne is decoded. Then, the server 7 transmits the decrypted second identification information I2A and I2N to the terminal device 3b via the network 6 and the access point (or base station) 5.

  As described above, the server 7 has the encryption key K1, and performs the decryption process using the encryption key K1 performed by the terminal device 3a shown in FIG. For this reason, security risks such as leakage of the encryption key K1 can be reduced.

[Second Modification of Second Embodiment]
Next, a wireless communication system according to a second modification of the second embodiment of the present invention (an example in which a server having the encryption key K1 encrypts the first identification information I1 and the random number Rb1) is shown in FIGS. Explanation will be made with reference to FIG.

<Configuration example of wireless communication system>
FIG. 12 shows a configuration example of a wireless communication system.
The radio communication system shown in FIG. 12 includes a server 8 in addition to the beacon device 1c and the electronic device 9 shown in FIG. 8, the terminal device 3b and the access point (or base station) 5 shown in FIG. Is done.

The storage unit 32 of the terminal device 3b stores preset first identification information I1 and encrypted second identification information I2Ae received from the server 8, and does not store the encryption key K1.
The server communication unit 36 transmits the first identification information I1 and the random number Rb1 received from the beacon signal B1 to the server 8 via the access point (or base station) 5 and the network 6, and the encrypted second identification is transmitted from the server 8. Information I2Ae is received.

  In this wireless communication system, the server 8 has the encryption key K1, and the server 8 performs an encryption process using the encryption key K1. For example, when the server 8 receives the first identification information I1 and the random number Rb1 from the terminal device 3b via the access point (or base station) 5 and the network 6, the encrypted second identification information I2Ae is obtained by the procedure shown in FIG. Is generated. Then, the server 8 transmits the encrypted second identification information I2Ae to the terminal device 3b via the network 6 and the access point (or base station) 5. Then, when the server communication unit 36 of the terminal device 3b receives the encrypted second identification information I2Ae from the access point (or base station) 5, the encrypted second identification information I2Ae is stored in the storage unit 32 of the terminal device 3b. deep.

  Thereafter, when the terminal device 3b receives the beacon signal B2 from the beacon device 1c, the processing unit 33 compares the content of the received beacon signal B2 with the encrypted second identification information I2Ae read from the storage unit 32. If the encrypted second identification information I2Ae is included in the beacon signal B2, since the comparison results are equal, the processing unit 33 confirms that the beacon signal B2 is the one when the beacon signal B2 is certainly transmitted from the beacon device 1c. The processing unit 33 (application A1) can execute a predetermined process. However, if the encrypted second identification information I2Ae is not included in the beacon signal B2, the processing unit 33 can confirm that the beacon signal B2 is not for the state notification transmitted from the beacon device 1c. In this case, since the beacon signal B2 is a signal when the state is not notified or is transmitted from another beacon device different from the beacon device 1c that transmitted the beacon signal B1, the processing unit 33 (application A1) Does not execute a predetermined process.

<Example of terminal device processing>
Next, a processing example of the terminal device 3b will be described.
FIG. 13 shows an example of processing until the terminal device 3b receives the first identification information I1 and the encrypted second identification information I2Ae, I2Ne and performs predetermined processing by the application A1.

Steps S401 to S403 and S407 in FIG. 13 are the same as steps S301 to S303 and S308 in FIG.
In addition, if the receiving part 31 has received the 1st identification information I1 in step S402, the receiving part 31 has also received the random number Rb1.

  After the application A1 is activated in the process of step S403, the application A1 transmits the first identification information I1 and the random number Rb1 to the server 8. Then, the application A1 acquires the encrypted second identification information I2Ae at the time of notification of the state of the electronic device 9 from the server 8 (S404) and stores it in the storage unit 32.

  Next, the application A1 waits for the encrypted second identification information I2Ae transmitted from the beacon device 1c (S405). And application A1 judges whether receiving part 31 received encryption 2nd discernment information I2Ae from beacon device 1c (S406). If the receiving unit 31 has not received the encrypted second identification information I2Ae, the application A1 returns the process to step S405.

  If the receiving unit 31 has received the encrypted second identification information I2Ae, the application A1 executes a predetermined process according to the notified state of the electronic device 9 (S407), and ends the process of FIG. .

  As described above, the server 8 has the encryption key K1, and performs the encryption process using the encryption key K1 similar to the encryption process performed by the beacon device 1c. The terminal device 3b receives the encrypted second identification information I2Ae from the server 8 and stores it in the storage unit 32. For this reason, the terminal device 3b does not need to decrypt the beacon signal B2 every time it receives it, and compares the encrypted second identification information I2Ae read from the storage unit 32 with the content of the beacon signal B2, and receives it. It can be determined whether or not the beacon signal B2 is the signal at the time of the state notification transmitted by the beacon device 1c. Further, since the server 8 has the encryption key K1, security risk such as leakage of the encryption key K1 can be reduced.

[Third Modification of Second Embodiment]
Next, FIG. 14 illustrates a wireless communication system according to a third modification of the second embodiment of the present invention (an example in which a terminal communication unit of a beacon device and a beacon communication unit of a terminal device communicate with each other). The description will be given with reference.

<Configuration example of wireless communication system>
FIG. 14 shows a configuration example of a wireless communication system.

Prepare.

This terminal device 3c does not have the encryption key K1.

The storage unit 32 stores preset first identification information I1 and encrypted second identification information I2Ae received from the beacon device 1d.
The beacon communication unit 37 can communicate with the terminal communication unit 16 of the beacon device 1d. Then, when the beacon communication unit 37 communicates with the terminal communication unit 16, the application A1 of the terminal device 3c performs the encryption second identification at the time of notification of the state of the electronic device 9, as shown in step S404 of FIG. Information I2Ae can be received from beacon device 1d.

  The second transmission unit 13 and the terminal communication unit 16 may be configured as one communication unit, and the reception unit 31 and the beacon communication unit 37 may be configured as one communication unit.

[Third embodiment]
Next, a radio communication system according to a third embodiment of the present invention (an example in which an advertisement packet in the BLE standard is used as a beacon signal) will be described with reference to FIGS. 15 and 16.

<Configuration example of wireless communication system>
FIG. 15 shows a configuration example of a wireless communication system.
The wireless communication system shown in FIG. 15 includes a beacon device 1e and a terminal device 3d.

The beacon device 1e includes a processing unit 17 in addition to the storage unit 11, the first transmission unit 12, and the terminal communication unit 16 included in the beacon device 1d illustrated in FIG.
The storage unit 11 stores first identification information I1. The first identification information I1 is read by the first transmission unit 12 and the terminal communication unit 16.
The terminal communication unit 16 includes the function of the second transmission unit 13 of the beacon device 1d illustrated in FIG. 14, and transmits the beacon signal B2 by broadcast and performs unicast communication with the beacon communication unit 37 of the terminal device 3d. Used for.
The processing unit 17 is configured by, for example, a central processing unit (CPU) that can be driven with low power consumption. The processing unit 17 can control the operation of each unit in the beacon device 1e based on the program, parameters, and the like read from the storage unit 11.

The terminal device 3d includes a storage unit 32, a processing unit 33, an input unit 34, an output unit 35, and a beacon communication unit 37 included in the terminal device 3c illustrated in FIG.
The beacon communication unit 37 includes the function of the reception unit 31 of the terminal device 3c illustrated in FIG. The beacon communication unit 37 can receive a beacon signal B1 from the first transmission unit 12 of the beacon device 1e and can communicate with the terminal communication unit 16 of the beacon device 1e.

  Here, as a communication standard used between the first transmission unit 12 and the beacon communication unit 37 and between the terminal communication unit 16 and the beacon communication unit 37, for example, a short distance such as Bluetooth (registered trademark) or BLE. Wireless communication standards are suitable.

The first transmission unit 12 of the beacon device 1e transmits an ADV_NONCONN_IND packet (an example of a first advertisement packet) that includes the first identification information I1 and does not accept a connection request in the BLE standard as a beacon signal B1. Also, the terminal communication unit 16 of the beacon device 1e transmits an ADV_IND packet (an example of a second advertisement packet) that includes the second identification information I1 and accepts a connection request in the BLE standard as a beacon signal B2.
The ADV_NONCONN_IND packet and the ADV_IND packet differ only in the packet type (PDU Type).

  The second identification information I1 may be determined based on the first identification information I1, or the second identification information I1 may have the same content as the first identification information I1. FIG. 15 illustrates an example in which the terminal communication unit 16 transmits and receives the same second identification information I1 as the first identification information I1 to and from the terminal device 3d.

  Then, when receiving the ADV_NONCONN_IND packet including the first identification information I1, the terminal device 3d sets the application A1 corresponding to the first identification information I1 to a reception waiting state for the ADV_IND packet. Further, when receiving the ADV_IND packet including the second identification information I1, the terminal device 3d executes a connection process for the beacon device 1e according to the second identification information I1.

<Example of terminal device processing>
Next, a processing example of the terminal device 3d will be described.
FIG. 16 shows an example of processing until the terminal device 3d receives the first identification information I1 and the second identification information I1 and connects to the beacon device 1e.

  First, the processing unit 33 waits for the first identification information I1 included in the ADV_NONCONN_IND packet through the beacon communication unit 37 (S501). Then, the processing unit 33 determines whether the beacon communication unit 37 has received the first identification information I1 (S502). If beacon communication part 37 has not received the 1st discernment information I1, processing part 33 continues processing of Steps S501 and S502.

  When the beacon communication unit 37 receives the first identification information I1 and the application A1 is not activated, the terminal device 3d controls the processing unit 33 to control the predetermined application according to the received first identification information I1. A1 is activated (S503), and the application A1 is placed in a standby state for receiving the second identification information I1. If the application A1 has already been activated, the process proceeds to subsequent step S504.

  Next, the application A1 in the reception standby state waits for the second identification information I1 included in the ADV_IND packet through the beacon communication unit 37 (S504). Then, the application A1 determines whether the beacon communication unit 37 has received the second identification information I1 (S505). If the beacon communication unit 37 has not received the second identification information I1, the application A1 continues the processes of steps S504 and S505.

  When the beacon communication unit 37 receives the second identification information I1, the application A1 performs a connection process to the beacon communication unit 37 so as to connect to the terminal communication unit 16 of the beacon device 1e according to the second identification information I1. Then, a predetermined process is executed in a state where the terminal device 3d and the beacon device 1e are connected (S506), and the process of FIG.

  The terminal device 3d according to the third embodiment described above receives the first identification information I1 and the second identification information I1 from the unencrypted ADV_NONCONN_IND packet and ADV_IND packet, respectively, and then the beacon device 1e Can be connected. While the terminal device 3d is connected to the beacon device 1e, the ADV_IND packet is not transmitted, but the beacon device 1e can continue to transmit the ADV_NONCONN_IND packet. For this reason, another terminal device 3d not connected to the beacon device 1e can start the application A1 by receiving the ADV_NONCONN_IND packet.
